Missing evidence for epidemics

It seems the more contagious form of plague has been infecting humans for nearly 4,000 years.

But there are no indications in the archaeological record of epidemics in the ancient societies in Russia and armenia — despite the fact that some individuals died from the highly contagious plague strain.

It’s possible outbreaks occurred but the evidence simply hasn’t been found yet. for example, if future excavations were to uncover a series of mass graves that differed from the usual burial customs of those cultures, this could suggest societal disruption consistent with an outbreak.
